基于 ExtJS 的 J2EE 轻量级框架的研究与应用

摘要

Currently popular Struts +Spring +Hibernate architecture provides a low coupling,easily maintainable and lightweight J2EE software development model,it can be used to build high-quality Web applications.Through studying SSH architecture and Ajax technology-based ExtJS framework,we design an integration framework which is based on ExtJS +SSH and is to be used to build a flexible, easily extended and maintainable multi-tier Web application platform,we also develop a commodities management support platform based on the integration framework.Experimental results show that this ExtJS and SSH-based integration framework completely separates the functions of display,business operations and database,so that achieves low coupling and high level maintenance of the system.%当前流行的 SSH（Struts ＋Spring ＋Hibernate）架构提供了低耦合的、易于维护的、轻量级 J2EE 软件开发模型，可用来构建高质量的 Web 应用。通过研究 SSH 架构及基于 Ajax 技术的 ExtJS 框架技术，设计基于 ExtJS ＋SSH 整合架构，用以构建灵活、易于扩展与维护的多层 Web 应用平台，并以此为基础开发了商品管理支持平台。实验结果表明：这种基于 SSH 与 ExtJS 整合架构将显示、业务运算、数据库等功能完全分离，从而实现了系统的低耦合性和良好的可维护性。
